This invention relates to a partition wall constructed of thin blocks orslabs of plastic material which are ada ted to be used in connectionwith a metalllc studding strip or reinforcing material which is fastenedto the ceiling and floor of a building and to which the slabs arefastened to form a rigid and substantial wall and this strip ispreferably a channel iron of any proper cross section.

Another object of the invention is to provide blocks or slabs of plasticmaterial with a tongue along one si e and edge of the slab and acorresponding groove on theopposite side and edge by means of which theslabs in a wall may be prevented from relative lateral movement withrespect to each other. v

For the attainment of these ends and the accomplishment-of other new anduseful objects, as will appear, the invention consists in the featuresof novelty in the construction, combination and arrangement .of theseveral parts generally shown in the accompanying drawings and describedin the specification, but more particularly pointed out in the appendedclaims.

In the drawings, Figure 1 is a view in elevation of a wall constructedin accordance with the principles of my invention; Fig. 2 is aperspective view, with parts broken away, of a block or slab constructedin accordance with the principles of my invenoion; Fig. 3 is a detailsectional view of part of 'a wall, as shown by Fig. 1, and Fig. 4 is asectional view of one of the slabs showing the means for connecting theslabs to the metal studding strips.

In the present embodiment of this invention the numeral 6 designatesgenerally a single block or slab of which the wall is constructed. Thisslab is comparatively thin in construction and is formed along one sideand the end edge with grooves 7 and 8, and along the opposite side andend edge with tongues 9 and 10. Extending transversely across the slabin the face thereof are grooves 11 at approximately onerouruiier thelength. of the slab soar the ends of'the slab.' These ooves extend lessthan half way through t e slab, and at approximately equal distancesfrom the edges of the slab is a. hole 12 with a rectangular depressionv13 in the face opposite the groove 11 to form a seat for the head of abolt.

1n constructing a wall of these slabs they are placed edge to edge withthe tongue of one engaging the groove of the other both at the sides andat the ends so that by staggering the slabs, as shown in Fig. 1, thetongue or groove connection will lock the slabs against lateral movementwith respect to each other and will hold them firmly in position. T hegrooves 11 in the face of the slabs are so placed that when the slabsare placed edge to edge or are staggered in the manner shown, the groovein the face of one slab will register with the groove; of a slab in thecourse below it, so that when the slabs are properly placed a groovewill be formed extending clear across the face of the wall formed by theseveral slabs. In order to hold the slabs securely in position a metalstrip 14 is seated in the groove and is formed with a foot 15 at theextremities by means of which the strip can be secured to a ceiling orfloor 16. A bolt 17 extends through the hole 12 in each slab and throughan aperture in the metal studding strip 14, the head ofthe bolt beingseated in the recess 13 in the face of the slab to prevent the bolt fromturning and also to provide a construction in which the bolt will beflush with the face of the slab. A nut 18 is threaded on the end of thebolt and against the metal studding strip 14, thus binding the slabreleasably but firmly to the studding strip, preventing its dislocationwith respect to the other slabs and forming a rigid partition wall whichis very simple in construction, which may be readily placed in positionand removed and which is very thin in construction thereby, economizingspace. It is obvious that this partition wall can be set up with orwithout the use of cement between the slabs, and it is -particularlyadapted for use without cement for the reason that the tongues andgrooves prevent the lateral dislocation of any of the slabs with respectto the others. By the constructions above set forth a wall is made whichpresents a finished appearance on both sides, the fastening andsupporting de vices of which do not project from the planes of the wallsurfaces and renders it possible to plaster, paper or aint over suchsurfaces. projections to mar or disfigure either surface.

\Vhat I claim is:

1. A partition wall construction comprising a series of slabs eachhaving end and side grooves and tongues to form interlocking joints andsuperposed in staggered relation, each slab having spaced apart verticalchannels across one face, said channels alining and forming continuousgrooves, studding strips countersunk in the grooves, bolts passingthrough each slab and strips from one side, nuts secured on the oppositeends of the bolts adjacent the studding strips, the bolt heads and nutsbeing countersunk within the surfaces of the slabs on both sides, andmeans for securing the upper and lower ends of the strips to a ceilingand floor respectively.

2. A partition wall construction comprising a series of slabs eachhaving end and When so treated t iere will be no side grooves andtongues to form interlocking joints and superposed in staggeredrelation, each slab having spaced apart vertical channels across oneface, said channels alining and forming a continuous groove, channeliron studding strips seated within said continuous grooves, said stripscountersunk in the'grooves, bolts passing through each slab, and stripsfrom one side, nuts secured on the opposite ends of the bolts adjacentthe stu'dding strips, the'bolt heads and nuts being countersunk withinthe surfaces of the slabs on both sides, and means for securing theupper and lower ends of the strips to a ceiling and floor respectively.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 3rd day of February A. D.1914.
